In agriculture and gardening, the germination rate describes how many seeds of a particular plant species, variety or seedlot are likely to germinate over a given period. It is a measure of germination time course and is usually expressed as a percentage, e.g ...
Using thermal and chemical scarification, germination increased to 48.8% and 44% respectively. 68% of Longspur lupine seeds germinated in the control group, while all scarification methods decreased the success rate of germination. The silvery lupine had 52% of its control group germinate but through mechanical scarification it rose to 85.2%.
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo.This is a pertinent stage in the plant life cycle that is followed by dormancy and germination. [1]
